Some of these greenhouses plans and types of materials that green house kits are built from include;


1 – Cold Houses

The term cold house refers to a greenhouse construction plan that focuses on protection for plants due to low temperatures, but only by a small amount since there’s no heat source. This plan is used primarily to allow gardeners to start spring crops a few weeks earlier. These can often be cheaper to make.

2 – Cool Houses

This greenhouse construction plan is warmer than a cold house. With this plan, you can get a lot more plants in wider ranges, but you need to actually have more of a way of heating the house. The temperature here is around 45 degrees Fahrenheit, and this type of house is used to house frost sensitive plants.

7 – Even Span

This greenhouse type is also attached to the side of a house. It’s different from a lean-to in that it’s a full structure that’s just attached to a building at one end. The air circulation in this type is usually better than in the lean-to design. This type also often has benches for crops to grow on. The shape is more ideal for keeping temperatures in the right uniform range as well. An even-span greenhouse can be made larger, and it has a lot of space, even though it is more costly to build. It’s known for making the best use of limited space.

8 – Window Mounted

These greenhouses are usually on the south or east side of a house. They can be attached to the house, and they are made completely of glass or clear plastic to let in light.

10 – Gothic

Gothic greenhouse types are focused on having the largest growth area possible, as well as effective distribution of natural light. They have arched roofs and can withstand winds up to 150 Km/h. There is some variation of roof type, including not having a roof window, or having a single or double window. These are usually more commercially oriented, with computer-operated systems that are automated. They are particularly useful for a fluctuating climate, areas with snow, rainy areas, or areas with very high wind.

The sawtooth design merges ventilation optimization with the ability to take on very heavy loads. This design has a series of arches that looks like a saw tooth from above, which is how it gets its name. The advantage of this style is that it’s quite easy to put together and keep going. The optimization of heat and humidity release makes this type more suitable for climates that are very warm.

In the end, the type of greenhouse you’ll want to build will depend a lot on your needs.

Commercial and hobby greenhouses are extremely different, for example.

Hobbyist greenhouses are often the kind that attach to your house, so they can often depend a lot on the shape of your house, and whether it can accommodate such a structure. IN some cases it may be wiser to connect a greenhouse to your house during construction of the house, especially in the case of particularly strong and inflexible greenhouse plans.
